Central nervous system findings by magnetic resonance in children with profound sensorineural hearing loss

A significant proportion of our patients being investigated by magnetic resonance imaging for profound sensorineural hearing loss show migrational abnormalities of the central nervous system, suggesting a central origin to their hearing loss. Some of these findings may result in neurodevelopmental delay and hence, negatively impact the success of cochlear implantation. We propose that magnetic resonance imaging of the temporal bone as part of the evaluation protocol for cochlear implantation in children should include central nervous system screening.
